Review: Perfect! - Works without any fuss with my QNAP 25Gb switches / NICs (I believe these are rebranded Mellanox units, or at least using Mellanox chips). I have been purchasing 10Gtek optics and DACS for some time, in 1G/10G and 25G variants and they have always been excellent. I would recommend them to anyone.
Review: Doesn't auto-negotiate down to 10Gb as details say it can....? - Got one of these in a Mellanox ConnectX-4-Lx card and it won't negotiate down to 10Gb talking to a 10gb 10Gtek module in my TP-Link 3008 - don't know why as it's supposed to be able to. Updated the card with the latest firmware (in case that was the issue) and still no joy. Gave it 3 stars as I will keep the module and when I upgrade the switch to 25Gbe I will try again then and my other 10Gtek modules have worked flawlessly so maybe it's user error?

### ⭐⭐⭐⭐⭐ Perfect!
*by R***G on 3 June 2023*

Works without any fuss with my QNAP 25Gb switches / NICs (I believe these are rebranded Mellanox units, or at least using Mellanox chips). I have been purchasing 10Gtek optics and DACS for some time, in 1G/10G and 25G variants and they have always been excellent. I would recommend them to anyone.

### ⭐⭐⭐ Doesn't auto-negotiate down to 10Gb as details say it can....?
*by C***S on 3 November 2025*

Got one of these in a Mellanox ConnectX-4-Lx card and it won't negotiate down to 10Gb talking to a 10gb 10Gtek module in my TP-Link 3008 - don't know why as it's supposed to be able to. Updated the card with the latest firmware (in case that was the issue) and still no joy. Gave it 3 stars as I will keep the module and when I upgrade the switch to 25Gbe I will try again then and my other 10Gtek modules have worked flawlessly so maybe it's user error?

### ⭐⭐ Major compatibility issues with Ubiquiti
*by I***E on 26 June 2024*

Beware before purchase! Initially I ordered 2 and they seem to work fine until I start to notice performance issues. It took me some time to trace the issue down to an incompatibility between these transceivers and Ubiquiti switches. I ordered 4 more which all show the same major performance issues (down to ~ 30 Mbps under some circumstances. I have tried several other brands including Ubiquiti transceivers and they all work fine. None of these 10GTek work without a problem. I mailed support via their website, They boast good technical support but I never got a reply. I can return 4, but the first order I can no longer return and there is no support. Think twice! Pay a little more.
